Interactions between organisms can take a variety of forms, from competition and conflict to cooperation. While cooperation among relatives is both well documented and relatively well understood in everything from slime molds to primates, cooperation among unrelated individuals, especially those that also compete directly with one another, remains more puzzling. The proposed research will study what social and environmental factors cause unrelated male marine fish to either cooperate or compete with one another. This research will also identify the genes, brain regions and hormones that control these behaviors - currently, there is little specific information on these mechanisms - and measure how cooperative versus competitive interactions affect reproduction in this species. Understanding what shapes cooperation, competition and conflict is not only of general interest, but can also inform conservation and management because negative interactions such as conflict and competition have been shown to increase a species risk of extinction. This project supports the training of undergraduate and graduate students on a variety of biological methods including field research on marine fish and tools for understanding the genes underlying social behavior. The professors and students involved in this research will also offer internships to high school students, education outreach lectures and online activities aimed at women and girls interested in science fields and careers. Several involved students will be from an undergraduate-focused institution which draws a number of non-traditional STEM students which will allow these students direct training opportunities that they otherwise would not have access to.The long-term goal of our research is to understand how social interactions and selection interact to shape variation in reproductive behaviors. We aim to quantify male plasticity in social behavior, document neural and hormonal mechanisms underlying plasticity in male social behavior, and determine how variation in male social interactions affects selection. To address these aims, we propose research on wild-living ocellated wrasse (a marine fish, Symphodus ocellatus). Ocellated wrasse males exhibit three alternative reproductive types: 'nesting males' provide parental care, defend territories, and form cooperative associations with unrelated 'satellites', who cheat by sneaking fertilizations but help by reducing reproductive competition from 'sneakers' (who do not cooperate or provide care; Stiver & Alonzo 2013). We adopt an integrative approach that allows us to examine the reproductive fitness consequences of variation in cooperation and competition and identify neural and hormonal mechanisms underlying this variation and behavioral plasticity.

生物之间的相互作用可以采取多种形式，从竞争和冲突到合作。虽然从黏菌到灵长类动物，近亲之间的合作都有很好的记录，也相对容易理解，但不相关个体之间的合作，尤其是那些直接相互竞争的个体之间的合作，仍然令人费解。拟议中的研究将研究是什么社会和环境因素导致不相关的雄性海洋鱼类相互合作或竞争。这项研究还将确定控制这些行为的基因、大脑区域和激素——目前，关于这些机制的具体信息很少——并测量合作与竞争的相互作用如何影响这个物种的繁殖。了解是什么形成了合作、竞争和冲突不仅是普遍的利益，而且还可以为保护和管理提供信息，因为冲突和竞争等负面互动已被证明会增加物种灭绝的风险。该项目支持本科生和研究生在各种生物学方法方面的培训，包括对海洋鱼类的实地研究和了解社会行为背后的基因的工具。参与这项研究的教授和学生还将为高中生提供实习机会、教育拓展讲座和针对对科学领域和职业感兴趣的妇女和女孩的在线活动。一些参与的学生将来自以本科为重点的机构，该机构吸引了许多非传统的STEM学生，这将为这些学生提供直接的培训机会，否则他们将无法获得这些机会。我们研究的长期目标是了解社会互动和选择如何相互作用，形成生殖行为的变化。我们的目标是量化男性社会行为的可塑性，记录男性社会行为可塑性背后的神经和激素机制，并确定男性社会互动的变化如何影响选择。为了实现这些目标，我们提出了对野生细胞濑鱼（一种海洋鱼类，Symphodus ocellatus）的研究。卵化的雄隆头鱼表现出三种可选择的生殖类型：“筑巢的雄隆头鱼”提供亲代照顾，保卫领地，并与不相关的“卫星鱼”形成合作关系，后者通过偷偷受精来欺骗，但通过减少来自“运动鞋”（不合作或不提供照顾；Stiver & Alonzo 2013）的生殖竞争来帮助它们。我们采用了一种综合的方法，使我们能够检查合作和竞争变化的生殖适应性后果，并确定这种变化和行为可塑性背后的神经和激素机制。
